VALVE -RE GULA'IOR.

Application filed April 16,

To all whom it may concern:

Be it known that I, GILBERT R. MILLER, a citizen of the United States,residing at Butler, in the county of Butler nd State of Pennsylvania,have invented certain new and useful Improvements in Valve-Regulators;and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the figures of reference markedthereon, which form a part of this specification.

My invention relates to certain new and useful improvements in valves,being more particularly applicable to the rotary class of valves.

The primary object involved in my invention, and which I proposecarrying out in the following described manner, is the adaptation of adevice whereby the valve,

which controls the admission of gas, or other similar fuel, to theengine, can be so regulated, and adjusted, that the minimum and maximumquantity of gas passing therethrough is under the control of theengineer at all times, and under all conditions; even though the saidengineer is stationed som distance away from the engine house.

Another feature involved is the double adjusting means for regulatingthe movement of the operating lever.

These features, above enumerated, will be of great advantage in oil andgas well drilling, or in fact any similar undertaking where it becomesnecessary to regulate the supply of gas when the engine is running lightor under load, and when the operator is at some distance from the engineroom.

In the accompanying drawing, forming a part of this specification, lhave shown several detail views of my invention: Figure 1 being a frontview in elevation; Fig. 2 a similar view with the dial plate adjusted atan angle; 3 a side elevation partly in section.

Throughout the drawings numerals of reference designate like parts, inwhich the numeral 1 is an ordinary straightnvay valve casing in which isoperatively seated the valve stem 2, having the V-shaped notch 3 formedtherein. The formation of this valve is not an essential part of myinvention, but is used as a convenient adjunct to the more particularfeatures which follow.

i In the form shown in Figs. 1, 2, and 3, the casing 1 is provided atone side with an integrally formed bearing and securing plate 4, incontact therewith being the dial plate 5, having formed thereon agraduated scale 6. This said plate is provided with arcuate slots '77,through which, and like- I wise through the plate 4, seat the securingbolts 8. The central portion of the plate 5 is also provided with anopening. to receive the valve stem 2. On the outer end of said valvestem, which is preferably in ade square or hexagon, is mounted a twopronged lever arm 9, to each end of which. is connected the operatingcable 10, and in its central part it is provided with an indicator orpointer 9, the utility of which will be readily apparent. Formed on thesaid plate 5 are a pair of standards 12, or housings, which areinternally threaded to receive the set screw 13, each one being providedwith a jam nut 14. The operation of my device is as follows: The setscrews 13 are iirst adjusted in their bearings so that their inner endswill limit the movement of the lever arm 9. In Fig. 1 the position ofthe said lever arm in full lines being shouldered agat st the set screw13, is when the valve is opened to the maximum limit desired to admitthe necessary volume of to operate the engine running under full load,and the position. in dotted lines, also shown as being shoulderedagainst the opposite screw, indicates that the valve closed sufficientto admit only the minimum amount of gas necessary to operate the enginewhile running with a reduced load. The o erator, being presumably atsome distance away from the regulating valve, has simply to draw on, forexample tile upper strand of the cable to open the valve to itspro-determined limit, see ful lines l 1, and in order to shut off thesupply he pulls on the lower strand, when the l ver arm 9 will bebrought into the position shown by dotted lines Fig. 1, and therebyclose the valve sul'liciently to allow only the minimum amount of toflow to the engine. r

it will readily be seen that by turning the set screws either inwardlytoward each other, or else in the reverse direction away from eachother, the distance between their inner ends is correspondinglydiminished or increased, and by so doing the movement of the lever arm 9is limited. This in turn naturally sets up the limitation for themovement of the valve stem 2, and as heretofore llO described, governsthe quantity of gas being admitted to the engine.

The secondary adjusting means, provided in the dial plate 5, wherebythat member may be turned at an oblique angle to the valve easing 1, asshown in Fig. 2, afi'ords a means for diminishing the movement of thelever arm in the direction of the full open po sition, withoutdisturbing the set screws, and consequently a reduced amount of gas willflow to the engine at the extreme forward position permitted the saidlever than will 'occur when the dial plate is in alinement with thevalve casing, as shown in Fig. 1. Likewise, in the arrangement of )artsshown in Fig. 2, on the movement of t 1e lever arm to its'reverselimitation, a less amount of will flow through the valve to furnish theminimum quantity to the engine.

In the form shown in Fig. 4 I dispense with the secondary adjustingmeans, heretofore described, and form the dial plate 5 as an integralpart of the valve casing.

I do not limit myself to the exact construction shown in the drawings,and heretofore described, as various alterations are possible in thedetail forms claimed without departing from the fundamental ideasinvolved. For instance, a solid connection may be made with the leverarm 9 in place of the cable I means here shown, and likewise various Iforms of adjusting screws may be substituted for those described.

1 Referring to the cable means for operating the lever arm I 9 it isunderstood that the same will be passed over or around a suitable lWheel,not shown,and convenient to the l operator.

a Having thus fully described and shown my invention, what I claim, anddesire to secure I by Letters Patentg is;

, In a valve regulating device, the combination, with the valve, of adial plate adjust ably secured thereto and provided with arcuate slotsto allow for said adjustment; a l two pronged lever arm secured to thevalve l stem having an indicator point formed thereon; suitable housingsformed at opnosite sides of the dial plate; adjustable screw memberspassing through the housings to limit the movement of the lever arm; andmeans connected to each arm of the lever for operating the same at adistance.

in testimony whereof, I aliix mysignature, in presence of two witnesses.
